.To cti/Z whom, it may concern:

Be it known that I, FRANK I-I. LINDEN- BERG, a citizen of the United States, residing at Columbus, in the county of Franklin and State oi' Ohio, have invented a certain new and useful Improvement in Closet-Tanks, of which the followinlT is a specification.

My invention re ates to the improvement oi' water-closet tanks, and has particular relation to the means for securing the sheetmetal lining thereof to the wooden body.

The object of my invention is to provide improved means for connecting the sheetcopper or other metallic lining of a tank of this kind with the body of the tank, and by such connection to permit of any warping or shrinkage in the wood of the tank without injury to the metallic lining or without separating the same at its seams or pulling said lining away from the bottom of the tank. This object I accomplish in the manner illustrated in the accompanying drawings, in which v Figure 1 is a central vertical longitudinal section of a tank having my improvement in connection therewith. Fig. 2 is a transverse section of the same, and Fig. 3 is a view in perspective of the tank.

Similar numerals refer to throughout the several views.

It has been customary to rigidly secure the sheetcopper or other metallic lining to the body of a closet-tank by nailing, tacking, or otherwise permanently connecting the upper portion oi' the lining sides and ends with the wooden tank-body; but experience has shown that the tendency of the sides and ends of the wooden body of the tank to bulge or warp from dam ness or other causes results in straining t e metallic lining and in pulling the same away from the bottom of the tank or breaking the lining at the seams. To overcome this dil'liculty, I have provided. the construction herein shown and described.

In carrying out my invention the tank 1, which is of any suitable form or construction, is provided with the usual sheet-metal similar parts means for said vertica lining 2, the sides and ends ol which extend to near the tops of the sides and ends of the tank-body. In securing this lining in place 5o I employ a desired number of disks or suitably-shaped plates 3, preferably metal, through the centers of which are driven or with which are formed tack or spur-like projections 4, the latter being driven into the inwill be understood that the usua outward or u ward bulge or swelling of the Wood from tllie sides or ends of the tank may take place without imparting sufficient pull on the lining to draw the latter out of its seat in the tank or to cause a separation of said lining. 7o

It will readily be seen that this result is due tothe fact that the connection between the lining and tank is not rigid and that the edge of the lining has sufficient play or sliding movement beneath the overlapping portions of the disks or plates 3 t0 permit of an u ward or outward bulging of the wood witliout drawing upon the lining.

Having now fully described my invention, what I claim, and Patent, is*

A tank, comprisin attached sheet-meta and inner sides of said she a wooden shell, an unlinin for the bottom l, means on said shell for holding the upper edge ofsaid lining with freedom of vertical movement in respect to the said shell and holding means, and space between said up er edge and confining movement.
